The pneumatic workbench part is the key part of the precision panel saw.It is also the main part that distinguishes it from ordinary circular sawing machines. The mobile workbench is composed of brackets, lower rails, rollers, push tables, etc. Its distinctive characteristics are: (1) Light operation and labor-saving, large push stroke, and large cutting width.;

(2) It is equipped with a stable and lightweight trailer, which runs smoothly; (3) The setting of the mobile workbench and the main saw blade can be adjusted by 45 degrees, which expands the scope of use of the saw machine. Some saw machines are also equipped with milling devices, which can process grooves and enterprise mouths with a width between 30-50MM.

3The use and operation characteristics of precision panel saws

Fine-cut panel saws are dynamically balanced or statically balanced. Under normal circumstances, no foundation is required, and they can be added on a flat ground.During processing operations, the workpiece is placed on the mobile workbench and the mobile workbench is manually pushed to enable the workpiece to realize the feed movement.The operation is very convenient, flexible and flexible, and safety should be paid attention to at all times when operating and using to prevent accidents.

4The main technical parameters of precision panel saws

The specifications of precision panel saws have become a series. The main parameters are zui large saws plus length, and the general range is 2000~5000. China's industry standard JB/T9950-1999 "Woodworking sawing machine Parameters with Mobile Workbench" stipulates three specifications of 2000mm, 2500mm, and 3150mm.

5The direction of efforts to design precision panel saws

Since the early 1980s, our country has introduced, developed and produced precision panel saws. Now there are more than 20 woodworking machinery manufacturing enterprises that produce precision panel saws, with an annual output of about 4,000 units. Basically, it has replaced imported products to meet domestic demand.

At present, most of the companies that produce precision panel saws in our country start the design of precision panel saws from surveying and mapping foreign prototypes, and then make improvements based on the problems that arise in their use. Some force relationships are not thoroughly understood, and there is blindness.The vast majority of enterprises have not carried out static and dynamic mechanical calculations, and lack the necessary theoretical basis.In order to improve the shortcomings in the design, a precision panel saw with good performance is designed.It is recommended that the main manufacturers of panel saws, #production companies, on the basis of summarizing existing experience, adopt the internationally popular CAD design, optimized design, dynamic design, and conduct pilot trials.At present, computing technology has gradually matured with the rapid development and application of juice computers. Finite element software is used to calculate the stress of precision panel saws under various complex forces.As far as the main saw blade and the scribing saw blade are concerned, the shape is not complicated. It can be roughly regarded as an elastomer. The vibration characteristics of the stress are calculated. At the same time, it is matched with the test and analysis technology card to obtain modal parameters and improve the calculation accuracy.On this basis, commercial software for the design and manufacture of precision panel saws can be developed, so as to design and manufacture high-level precision panel saws on the basis of actual theoretical basis.

At present, the representative companies that can apply advanced design tools to independently develop new types of panel saws in China are: Qingdao Yongqiang woodworking machinery, Mars woodworking machinery, Nanxing woodworking machinery, etc.On the basis of digesting and absorbing advanced foreign models, these representative companies have developed and produced a number of representative products based on the specific needs of the domestic market, such as Qingdao Yongqiang's MV8-90, Mars' MJ6132, Nanxing's MJ6132Y and so on.
